Find f(6) if f(x) = x^2 ÷ 3 + x.

Answers

Hello,

f(x)=x²/3+x
==>f(6)=6²/3+6=36/2+6=12+6=18

Answer C

Answer:

Step-by-step explanation:

Remember to use the order of operations.

First, write 6 wherever there is a X in the original equation. We know to do this because the ''f(6)'' tell us what X is. 6^2 / 3 + 6

Second, we need to find the answer to 6 x 6 or 6 squared. Rember that when you see 6^2, it does not mean 6 x 2. It means that number, times itself. 6 x 6 = 36

Now our equation looks like this. 36 / 3 + 6

Third, we divided 36 by 3. 36 / 3 = 12

Now our equation looks like this. 12 + 6

Finally, we add 12 + 6 together for our final answer. 12 + 6 = 18

CANT GET WRONGJason is training for a marathon bike ride. His average speed increased from 3 miles per hour to 6 miles per hour in 3 months. Find the rate of change in the miles per hour that Jason bikes. A) .5 mile per hour per month B) 1 mile per hour per month C) 2 miles per hour per month D) 3 miles per hour per month

Answers

Answer: The correct option is (B) 1 mile per hour per month.

Step-by-step explanation: Given that Jason is training for a marathon bike ride. His average speed increased from 3 miles per hour to 6 miles per hour in 3 months.

We are to find the rate of change in the miles per hour that Jason bikes.

We know that

the average rate of change between the points (a, b) and (c, d) is given by

$A_r=(d-b)/(c-a).$

Since the number of months vary from 0 to 3, and the speed increases from 3 miles per hour to 6 miles per hour,

so the two points on the co-ordinate plane with number of months plotted across X-axis and average speed plotted on Y-axis are (0, 3) and (3, 6).

Therefore, the average rate of change in the miles per hour that Jason bikes is

$A_r=(6-3)/(3-1)=(3)/(3)=1.$

Thus, the required rate of change is 1 mile per hour per month.

Option (B) is correct.

B.... 6-3=3miles in 3 months .. and that's a mile per month

In hoping to make it onto the school's Gold Team, Bryan, Eli,and Damien took golf lessons over the summer.Bryan signed up to take 4 lessons with a semi-pro instructor, and each lesson cost $32.00 for a 45-minute session. The instructor advised Bryan to buy a bag of bulk practice balls to use during his lessons. After buying a bag of 32 golf balls, the total cost for his lessons and golf balls is $132.48.
Eli signed up to take 6 lessons with a pro instructor, and each lesson cost $52.00 for a 1-hour session. Eli bought a bag of bulk practice balls to use during his lessons. After buying a bag of 40 golf balls, the total cost for his lessons and golf balls is $319.20.
Damien signed up to take 5 lessons with pro instructor, and each lesson cost $28.00 for a 30-minute session. Based on the instructor's advise, he bought a bag of 24 golf balls to use during his lessons. The total cost for his lessons and golf balls is $144.08.
Place the students in order from the least amount to the greatest amount that they paid per golf ball.

Answers

bryan: 32*4 = 128

132.48 - 128 = 4.48

4.48 /32 = 0.14 per golf ball

Eli: 52 *6 = 312

319.20 - 312 = 7.20

7.20 / 40 = 0.18 per golf ball

Damien: 28*5 = 140

144.08 - 140 = 4.08

4.08 / 24 = 0.17 per ball

Answers

Answer: Cluster sampling

Step-by-step explanation:

A cluster sampling is a kind of random sampling technique in which the researcher splits the whole population into distinct sets known as clusters.

After that, he choose a random sample of clusters from the population and do analysis on it.

In the given situation, the objective of survey : "To determine customer opinion of their pricing:".

He first divides the number of check out lines according to weeks and randomly selects 140 check out lines during a certain week and surveys all customers in the check out lines. .

(Here , check out lines = clusters )

Therefore , the type of sampling is used = Cluster sampling

Cluster sampling is used by Home Depot for a certain week and surveys all customers in the check out lines.
